Mini PCs have clearly changed the way we view computing at home. A few years ago, having a powerful computer necessarily meant a noisy tower sitting under the desk. Today, machines barely larger than an internet box can run Windows, Linux, Docker, Home Assistant, Plex, or several network services without breaking a sweat.
We have already had the opportunity to test numerous mini PC models in recent years. And honestly, these little machines have become real Swiss army knives. Some use them as a discreet family PC in the living room, others as a home automation server 24/7, lightweight NAS, Proxmox machine, 4K multimedia box, or even an ultra-energy-efficient Docker platform.
One brand kept coming up in discussions among enthusiasts… but we had never had the chance to discover it: GMKtec. The manufacturer has just announced its new high-end model, the GMKtec NucBox M3 Pro, a mini PC particularly interesting on paper.
GMKtec, a rising brand in the mini PC universe
The mini PC market has literally exploded over the past two or three years. It must be said that usage has evolved tremendously. Between telecommuting, virtualization needs, personal servers, home automation systems, and multimedia platforms, many now seek compact, quiet, and energy-efficient machines.
GMKtec has specialized precisely in this area. The brand develops mini PCs focused on productivity, multimedia, edge AI, and intelligent domestic use.
The positioning is interesting: offering powerful configurations in ultra-compact formats, with a price generally more aggressive than some well-known references in the sector.
And clearly, this new M3 Pro seems to want to check a lot of boxes.
An Intel Core i5-13500H in a tiny form factor
The heart of this new model rests on a 13th-generation Intel Core i5-13500H processor. We’re talking about a CPU with 12 cores and 16 threads, capable of reaching up to 4.7 GHz.
In other words: we are far from the sluggish small PC reserved for light office work.
This type of processor allows for a vast range of different uses without frustration. For a Home Assistant server with several resource-intensive extensions, Docker containers, an MQTT server, Node-RED, a Frigate NVR with AI acceleration, or even a Proxmox installation with multiple VMs, the configuration seems more than sufficient.
Even on the multimedia or advanced office side, the M3 Pro has what it takes to keep up. 4K streaming, browsing with dozens of tabs, light photo editing, Office suite, occasional video editing… this little box should handle it all with ease.
And perhaps the most impressive aspect remains its size. GMKtec announces a form factor representing about 1/50th the size of a classic desktop PC.
For those looking to declutter a desk or integrate a discreet server into a network rack or TV stand, this is typically the kind of machine that catches the eye immediately.
An ideal configuration for Home Assistant and Docker?
It’s hard not to think immediately of home automation when discovering the technical sheet of the M3 Pro.
In recent years, many users have transitioned from Raspberry Pis to more powerful and, above all, more reliable mini PCs on the long term. With NVMe SSDs, modern processors, and expandable memory, these machines offer enormous comfort.
The GMKtec M3 Pro can accommodate up to 64 GB of DDR4 RAM via two SO-DIMM slots.
Storage is also very flexible with an M.2 NVMe 2280 slot and a second M.2 2242 SATA/PCIe slot.
Concretely, this opens the door to very serious installations:
- Home Assistant OS under Proxmox
- Multi-service Docker server
- Light NAS under OpenMediaVault
- Plex or Jellyfin
- Frigate for AI surveillance
- VPN server
- Development platform or home automation lab
And with a built-in 2.5 GbE network port, the speeds should be more than sufficient for most modern network uses.
Wi-Fi 6 and Bluetooth 5.2 are also included.
Triple 4K display and modern connectivity
GMKtec has not forgotten office and multimedia uses.
The M3 Pro can manage up to three 4K displays simultaneously thanks to its two HDMI outputs and a USB-C port compatible with display.
For telecommuting, trading, home automation supervision, or simply comfortable multitasking, this is clearly appreciated.
The connectivity also seems quite comprehensive with several USB 3.2 Gen2 ports, a USB 2.0 port, an audio jack, and especially a full-function USB-C port that allows for both data and video display.
This is typically the kind of detail that greatly simplifies daily installation.
A compact yet well-designed unit
Another interesting point: GMKtec seems to have paid attention to the casing design.
The manufacturer announces a CNC metal chassis with a sandblasted finish and anti-fingerprint treatment.
The cooling system relies on a copper heat pipe and turbine ventilation with bidirectional air circulation.
On such a mini machine, thermal management is essential. Many compact mini PCs tend to overheat or become noisy when heavily utilized. This will need to be checked in real-world conditions, but the technical sheet seems reassuring.
Rather aggressive pricing
GMKtec announces several configurations for the launch of the M3 Pro, directly available in the official store.
The barebone version starts at around €319, while the pre-configured versions with memory and SSD go up to €439 for the 16GB + 512GB version, and €619 for the 32 GB / 1 TB model. (You can also benefit from an additional €15 discount with the code M3Pro15OFF.)
Given the embedded configuration, particularly the Core i5-13500H, the prices are quite competitive compared to certain market competitors.
GMKtec NucBox M3 Pro
And honestly, when we see the possible uses today with this type of machine, we understand why mini PCs are so appealing to home automation enthusiasts and home lab geeks.
A complete review will be coming soon on Maison et Domotique
On paper, this GMKtec M3 Pro looks particularly promising for those seeking a compact yet powerful machine, capable of handling both daily office work and a true home server.
The good news is that a review of one of the brand’s models will be coming soon on Maison-et-Domotique.com!
This will provide an opportunity to check its real performance, power consumption, noise level, capabilities under Docker or Home Assistant, and especially see if GMKtec can truly become an essential reference in the mini PC universe.
